Overview

• Commerce published a cryptographic hash of the BEA’s Q2 2025 GDP release—3.3% annualized growth—on nine chains, in some cases also posting the topline figure.
• The initial rollout spans Bitcoin, Ethereum, Solana, TRON, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism, with Coinbase, Gemini, and Kraken assisting publication.
• Chainlink and Pyth are distributing verified BEA data feeds, including real GDP, the PCE Price Index, and real final sales to private domestic purchasers, with updates on monthly or quarterly schedules across multiple networks.
• Officials describe the effort as a proof of concept that could extend to additional datasets and platforms as the program matures.
• The department says this is a first for a federal agency, though it has not detailed an ongoing technical plan, and analysts note blockchain ensures integrity of published data but not the accuracy of underlying collection.
